Patent GB-2495672-A (GB)
Title: Flash defrost system
Inventor: DAVIES THOMAS WILLIAM
IPC: F25B47/02
Filed: 2012-02-10
Abstract: A vapour compression refrigeration system includes a compressor (1) arranged to re-circulate refrigerant through a condenser (2), an expansion device (4) and an evaporator (5). To achieve rapid thermodynamically efficient defrosting of the evaporator, hot refrigerant from the condenser is stored in a defrost receiver (6) before passing through the expansion device (4). In a defrost phase, a valve arrangement (7-10) forms a closed defrost circuit connecting the evaporator (5) to the defrost receiver (6) via defrost valve (10) to allow hot fluid to pass from the defrost receiver to the evaporator and liquid refrigerant in the evaporator flows to the defrost receiver (6) via drain valve (9). In a pre-defrost phase, the valve arrangement closes the fluid input to the evaporator (5) and the compressor operates to partially evacuate the evaporator before the evaporator is connected to the defrost receiver, so that flash flooding of the evaporator with hot vapour occurs. A phase change medium (11) may be included to store heat from the condenser output and return it to the evaporator during defrost. Additional heat may be supplied to the defrost liquid to further increase the defrost speed.

Title: Scalability breakpoint calculator for a software product
Inventor: LAI RAY Y
IPC: G06F9/44
Filed: 2011-05-26
Abstract: During a technique for estimating a scalability breakpoint of a software product, performance load tests of the software product are performed with different numbers of simulated concurrent users. For a given number of simulated concurrent users, a performance load test may include an associated set of transactions that are executed by the software product. Furthermore, during the performance load tests performance metrics for the transactions in the associated sets of transactions are measured. Then estimated total performance metrics for the transactions in the associated sets of transactions for the different numbers of simulated concurrent users are determined based on the measured performance metrics and the associated sets of transactions. Next, using the determined estimated total performance metrics, the estimated scalability breakpoint is calculated.

Title: Generating test scripts through application integration
Inventor: RICHARDS GRAHAM
IPC: G06F11/36
Filed: 2013-04-26
Abstract: A test script generation method comprises first parsing a previous test script for a GUI, parsing a model associated with a GUI, and identifying GUI actions identified by keywords that exist in the pre-existing script, and generating a new test script by adding the identified actions. The parsing may be done with a natural language parser, and act upon a manually generated pre-existing script. GUI actions in the pre-existing script may be added to a candidate list, with only possible actions added to the new test script, where the action may be flagged. The new script may be generated from an empty template. If no matching GUI elements are found, then the process halts to allow a user to input the appropriate action; any successful decisions from the candidate list or user-input may be added to a keyword <-> element pair for future manual parsing.
